[Q] Help regarding undervolting in Siyah kernel - Galaxy S III Q&A, Help & Troubleshooting

I have SiyahKernel S3 v1.8.9 installed in my S3.
I have now installed " EvenMoreBatteryTweaksGovernor.zip " which is provided by gokhanmoral itself.
Now if i undervolt my phone to -25mV or -50mV will it affect my hardware ? as in my processor(all 4 cores)..will they have any negative effect ?

thanks for ur reply
I read about this guide and after reading this guide i am ready to undervolt but the main thing comes that i already have installed siyah kernel battery saving tweak. so i have a concern that now, if i undervolt my device, will that affect my hardware as in processors ?
i am new to xda else would have posted direct here

I'm not sure what you mean by affect your processor. If you mean performance, no uv doesn't affect your performance unless you set it too low then it gets unstable and goes into bootloop. So you'll wish to tread carefully when going into over -75mv.
As for long-term damage on the phone, I heard many people say differently. Might wanna search and see for yourself. Personally don't really think it'd damage the hardware if you uv a little.

yes, with 'affect on processor' i meant that after a time period will it affect my hardware or not. my processor will be in good condition or not.
btw thanks for ur reply. i will search more for the after affects of undervolting a phone.

How do I undervolt?

I'm rooted, how do I undervolt? Is there an app available?

SEARCH XDA AND GOOGLE. There are prolly a dozen threads on CPU clocking for your phone. (I'm assuming you mean underclocking, right?)

download a oc/uv kernel then install voltage control from the marker, I suggest eugenes dead horse kernel but that's just me.
btw Q&A

Underclock is NOT undervolt
and to the OP, please post in the right section

You can start by posting in the correct forum. Q&A... General...
Yeah, that would be a good start.
Yes post in Q & A next time please.
There are many apps on the market that will do this. Under-volting is just lowering the voltage to the cpu. The voltage standard setting is set based on the voltage that will work best for all manufactured cpus in a unit. Most of these chips are "low-bid" so the Q/C is not that accurate, so they set the voltage a little higher to make sure they always perform. Most of the tech savvy people know they can lower that setting....... and do so to lower temp and add to battery life.
Underclocking is something else entirely That is the cycle clock speed......... 2 different animals.

Xperia mini pro overclocking information

I want to know what's the safe overclocking maximum and governor . I also want to know what's the maximum safe temperature? Is 50c' as a maximum safe? Thanks for your help.

theres no such tthing as safe oc.
each and every cpu had different characteristic thus different capability when it comes to oc. what might works with others might just hardbrick yours. you just need to experiment yourself. do note thats its dangerous. earlier one guy already fried his phone when oc to 1.8ghz+playing gta3.
and for me personally 45c feels too hot already.

I know what you mean. You are right of course. Mine is overclocked to 1.3ghz governor smartassV2 and the max temp for overclocking is my problem now. I can't decide what is the max temp at which the phone should go back to 1ghz . Do you think 45c' as a maximum safe?
Sent from my SK17i using xda premium
then use any app that can create profile to automatically lower cpu freq based on temperature eg cputuner or setcpu.

I'm already using CPU master pro . I created a profile for overheating but I don't know what is the maximum temperature that I should use?
Sent from my SK17i using xda premium
I'd say 45° MAX. Or even less. And still you can't be 100% sure you won't have any problem.

Overclocking gpu

I noticed on the black star rom I have the option to overclock gpu. I am wondering if it is a good idea
Sent from my SAMSUNG-SGH-I717 using Tapatalk 2
GPU overclocking carries risk, just as does an overclock of the CPU...
There are many variables that can affect device performance to the negative.
Overclock of the GPU can increase performance, but at a price. Heat, shortening of lifespan etc. are always a risk. not to mention battery life.
It's really your call, but exercise caution whenever you drive a chip beyond it's intended limits. Often times the voltage bleeding will counter any real gains.
A bit more reading is warranted.....g
You have misunderstandings or over clocking. Over clocking, or running a processor at a higher than recommended bus speed or with an increased multiplier, does not, in and of itself, use more power or generate more heat. It can lead to decreased stability. Overvolting is the act of increasing the voltage of said processor in an attempt to increase stability at the cost of increased heat generation, shortened battery life, and possible hardware damage.
I see these misunderstandings perpetuated constantly all over the internet, but take it from those of us who have been over-clocking for decades.

You can use this one safely.
The AOSP-based ROMs (AOKP, CyanogenMod, etc.) are already overclocked and nobody has had trouble.

As someone who first ported GPU oc support to our note, I'm sure this is not the case. If you know something I don't, could you link the source to your information?

Hmm, perhaps I'm mistaken but I only deduced that because the gpu performance matched the overclocked performance of Blackstar.

low score :(

Hey!! Im running wannamlite latest rom with yank-s laatest kernel and just from curiosity I ran a benchmark test with Antutu,and my score was horrible, around 9800...and i saw that the gs3 has over 12-13000 ...what is my problem?

Benchmarks are unreliable ..
You have a custom rom and a custom kernel .
So why are you not asking the question in the relevant threads ???
jje
I never trusted benchmarks,but this one is so damn low.
Because I can ask almost everything I want in this thread.In rom/kernel thread just a part of the users answers,here a lot more people are watching so I might have extra chances xD.
Don't worry about benchmarks. Add long as real feel feels fast and not laggy then everything should be good
Sent from my GT-I9300 using xda app-developers app
But it does!Whatever rom/kernel I use,after like 2-3 days of use it becomes laggy.
I don't have more than 30 apps installed :-/
Last time I benchmarked I hit 17,000

nope,no power saving on.

Ok there are still other things you can do. Maybe something is eating your cpu. Try using cpuspy or setcpu to see what clocks your using. If its at the highest clock all the time that could indicate a cpu hog.
See what processes are using those high clocks with top or another program run on the phone.
Most important though is to see what is actualy causing the low score, which part of the benchmark is causing low scores. Maybe IO or memory performance, cpu might be fine.

[Q] Best kernel for underclocking

Which kernel is the best to use for underclocking my s3, by best i mean one which has tje least chance if sending my phone into bootloop or bricking it?
Why underclock?

R: [Q] Best kernel for underclocking
i have no idea why you would buy a high end phone to underclock....i gues u just wanna test it and see how low it can go before crashing(ur lucky cpu master has the option not to set cpu at startup).
My guess is...it will crash easily ciz touchwiz requires some perfornance to run smoothly.
Anyways i would guess the best for underclocking is also the best for overclocking...my kernel is syiah...try it.
If u f**k up something...u can still get the same low-end feeling of your underclocked s3 on a windows phone
Sent from my GT-I9300 using xda app-developers app
It really doesn't matter what kernel you use to under clock....1.2GHz is 1.2GHz.....regardless off the kernel, likewise, if you set voltages, it doesn't really matter what you do it with, add long as the kernel is capable of oc/uc.
I suggest doing some research before you start messing with stuff you don't understand

Buy a cheap Chinese s3 copy no need to underclock

I guess i phrased the question wrongly, my phone heats up very quickly and the battery runs out real fast, so i thought maybe i should underclock/undervolt... or should i just buy a new battery?

Something is causing that problem, most likely an app or the media scanner playing up, you need to eliminate all those things before you start looking at kernel side fixes

Firstly have you tried different roms and or kernels?
What kind of temperatures are you reaching?

R: [Q] Best kernel for underclocking
Yeah that sort of problem is caused by instability not overclock. Ive got my s3 overoverclocked(more than samsung's stock overclockment XD) and i dont get any heating.
Like the other dude said it's a problem within the system options...wil be difficult to find unless u installed something weird recently...
Only way is flash new rom and more stable/different kernel.
Sent from my GT-I9300 using xda app-developers app
Try Boeffla Kernel, best one IMO. Easy to use and very customizable.
But if your phone gets hot for no reason you should have it repaired. Mine had a similar issue, it heated until reboot. Sent it to be repaired, according to samsung it was a motherboard issue.
Thread closed as its a best kernel thread.
